Biometric data becomes the encryption key in Fujitsu system

Fujitsu says it has developed software that uses biometric data directly as the basis for encryption and decryption of data, simplifying and strengthening security systems that rely on biometrics such as fingerprints, retina scans and palm vein scans.

Current security systems that rely on encryption require the management of encryption keys, which are stored on secure smartcards or directly on PCs. Biometric scans can be used as a way of authenticating the user and providing access to those encryption keys in order to decrypt data.

Fujitsu's system uses elements extracted from the biometric scan itself as a part of a procedure to encrypt the data, making the biometric scan an integral part of the encryption system and removing the need for encryption keys.
